bookmark_borderEffects of Aging on the Eyes

When changes like this happen and you feel your eyesight is weakening, corrective measures can be taken to reduce the impact of it on your day to day life. For instance, you could add higher voltage lights in places you spend time in most, like around your house, the stairways and your favorite reading spots. This could help you reduce strain on your eyes and make you see a lot better. It will also reduce the chances of any accidents happening due to weak eyesight.

You can prevent eye problems and eye diseases by following the methods listed below –
Visiting your doctor and performing regular medical tests to check for diseases like diabetes, which is a silent killer and leads to problems in eyesight if not treated on time.

Conducting a thorough eye scan with your eye specialist once every year.

Almost all eye problems can be treated if they are found in the early stages. You should ensure that your eye doctor checks if your pupils are dilating, this is done by the use of eye drops. You should also have your doctor check your eyesight, your spectacles and the eye muscles. Its also very important that you conduct a Glaucoma test for the eyes.

If your are a diabetic or have a family history eye problems you should get your eyes checked thoroughly once every year through the dilated pupils eyes exam. You should also be very vigilant in spotting any dimness in eyesight, any sort of eye pain/pressure, fluids coming out from the eye, any sort of redness or double vision of your eye or swelling in the eyelid.

Listed below are eye conditions that many people experience over time-

Presbyopia is a condition that advents after the age of 40, many people tend to lose the ability to see near objects or read small prints; this is accompanied by headaches and the tiring of the eyes. This is a normal process that eventually happens to most of the people in their lifetime. Presbyopia can be corrected with wearing reading glasses.

Floaters are small dot like specks that float along with your field of vision. Floaters can be noticed in well lit rooms or outdoors on a bright day as well. This condition is normal but sometimes they can be warning indicator of a bigger underlying problem like detachment of the retina, especially if they are accompanied by bright flashes of light in front of your vision. If you feel you can notice a sudden change in the number of floaters, please consult your eye doctor rightaway.

Dry eyes is a condition that takes place when your tear glands do not create enough tears to lubricate the eye. Due to this a person may feel uncomfortable, and is tempted to itch the eyes. It can also result in a burning like sensation or subsequent loss of vision. Your eye doctor will suggest the use of eye drops to counter this and in some serios cases surgery could be required.

Tearing, is a condition that occurs when the eye tears a lot. This condition happens due to the sensitivity to light, wind, or temperature changes. You can protect the eyes by wearing sunglasses, which can lead to solving the problem. Tearing could also arise due to the underlining of a more serios problem such as an eye infection or a blocked tear duct. You must consult your eye doctor if you feel this is happening to you. Both of these conditions can be treated by your doctor.

Cataract is a condition by which certain or all parts of the eye become cloudy. This clouding of the eye lens stops light from passing through, which results in loss of eyesight. The formation of Cataract is usually slow and does cause any sort of pain or redness of the eye. Once the Cataract becomes large and thick it is advisable to have it removed surgically, where the doctor re-places the clouded lens with clear plastic lens. A Cataract surgery is very safe and one of the most common surgeries done in the United States.

Glaucoma is a condition that results from the excessive build up of fluid pressure within the eye. Glaucoma can result in loss of vision or complete blindness if not treated in the early stages. Most people suffering from Glaucoma do not have any early symptoms of the disease. Its thus important that you get your eyes checked for this disease. The doctor performs this check by dilating your pupils.

Some general health benefits of taking Magnesium include lower blood pressure. This is due to the fact that magnesium plays a role in regulating normal heart function. From this point of view it assists the heart as a natural remedy for heart palpitations due to the fact that it maintains a normal heart rhythm. It also helps you to maintain normal blood pressure. Concentrations of magnesium are also found in the bones and skeletal muscle. Therefore, this mineral supports bone health. Magnesium is also useful in the sense that due to the fact that it is considered a muscle relaxant it is used by athletes to alleviate sore muscles. There is also an application that applies to relieving anxiety and depression. For instance, a deficiency in this mineral causes these symptoms as this mineral also regulates the healthy function of the nervous system. It is also important in regulating energy levels and improving the health of the immune system. But did you know that Magnesium also supports eye health? Here are some eye health benefits of magnesium for better vision:

Helps in Absorption of various vitamins: magnesium is involved in absorbing Vitamins A, C and B and these vitamins play a role in maintaining the healthy function of ocular tissue in the eyes. This mineral works in conjunction with these vitamins to prevent oxidative stress in the eyes factors responsible for the development of cataracts.

Reduces Risks For Age Related Vision Disorders: Research suggests that magnesium reduces the risks for the age related vision disorders macular degeneration, cataracts and also diabetic retinopathy. A research study in the British Journal of medicine reveals that eating an extra portion and a half of green vegetables, which is a good nutritional source of this mineral, actually provides the body with 14% of your daily recommended allowance for this nutrient. Therefore, this is adequate enough to lower blood glucose levels in the body to normal levels. This is a factor that also leads to a reduction in the risks for diabetic retinopathy.

Magnesium is an essential nutrient that controls a variety of important functions in the body that are associated with the regulation of normal heart rhythm, blood pressure as well as the regulation of a properly working digestive system and immune system. This mineral also helps the eyes as well in terms of reducing the risks for various eye diseases and eye disorders such as diabetic retinopathy, macular degeneration and cataracts. This mineral should be taken in conjunction with calcium for best results.

Custom Lasik surgery involves photographing your cornea from three different dimensions to check on the comportment in which it recognizes and retains light. Doctors will appraise these pictures and the surgical stratagem for your Lasik surgery will be based on their annotations. This procedure is known as lasik wave-front technology and it offers better exactness and exactness match up to to contact lenses, glasses or other Lasik procedures.

But know that this may not be appropriate for everyone. You need to be accepted as a nominee for custom lasik surgery by the FDA. The stipulation of your eyes and general health will first be checkered by the FDA and then by your surgeon to verify if you are at all eligible for the procedure. Be conscious that lasik surgery though popular eyes care procedure today may also not be the solution to many indiscretions to do with vision.

Lasik in San Diego and Lasik institutes in Los Angeles are possibly the best options for most people keen on this procedure. Both cities are the largest in the state of California and come highly recommended for their excellent lasik doctors, lasik institutes, pre and post operative care and follow-ups.

Lasik costs depend on doctors, expertise, and institutes you prefer. While one lasik surgery brings about working only on one eye, the expenses will double if both eyes are operated. Lasik doctors and lasik institutes may also add charges reliant on whether lasik wave front examination is being used or not for that added precision.

bookmark_borderIritis

Iris is a curtain-like outer tissue encircling the pupil, behind the cornea. It is the one which gives the color to the eye which we describe variously as black eye, brown eye etc., Iritis or Iridocyclitis is a serious disease of the eye. Generally it is mistaken for simple conjunctivitis or red eye. As a result patient wastes plenty of time before consulting an Eye-specialist. The problem is if the patient starts treatment in the late phase of the disease, even the best of treatment will not prevent damage to the structure and function of the eye. In the anterior uveitis or iritis, the iris is affected in different grades depending on the severity of the disease. With the result, the pupil which is normally round gets deformed or go out of shape. Sometimes different types of exudates would accumulate in the papillary area or anterior chamber.

The Eye-specialist has to find the cause of iritis. He usually recommends blood and urine tests and, if the cough is severe then the sputum examination also has to be done. In spite of these tests, many a time the cause may not be detected. Then the treatment becomes difficult.

The Eye surgeon has to treat the patient empirically , with the assumption that the infection is somewhere in the body. Sometimes diseases like Syphilis, Gonorrhoea, Leprosy and Tuberculosis may be causative factor for the disease. Then the treatment becomes comparatively easy. Some allergic reaction in the body may also cause iritis.

Early diagnosis and treatment has beneficial effects. Steroid and atropine eye drops, systemic steroid ( steroid given in the form of tablets or injections) and systemic antibiotics are given. This requires a prolonged treatment. Some patients do not complete the course of the treatment, with the result the disease recurs. If the treatment is not taken properly or otherwise also due to the severity of the disease, there would be disastrous effects. Iris shrinks in different proportions resulting in what is known as synechia. The clear normal lens of the eye also gets affected resulting in complicated cataract causing complete blindness. If the disease goes beyond this stage, it would make the eyeball small and useless- Pthisis Bulbi. The treatment is not effective in advanced phase of the disease. That is why it is very important to diagnose at the early stage of the disease and institute methodic treatment, which would be helpful.

You may improve your blood circulation in many ways : do not smoke, the nicotine causes your blood vessels to constrict and your heart to beat faster, and this raises your blood pressure. Most people breathe improperly by using only the upper portion of lungs; Hydrotherapy (hot and cold shower) may help to improve blood circulation. Avoid stressful situations. Regular exercise will have positive results on your blood flow. Choose a diet that includes lots of fruits and vegetables and is low in fat. Reduce proteins and saturated fats (found in red meat, cheese and cream). Effective circulation boosting foods are pumpkin seeds , oranges, nuts, watermelon, garlic.

Improving sleep may also help to improve blood circulation, here are some tips to improve your sleep : Avoid large meals before bedtime, or going to bed feeling hungry. Avoid sources of caffeine such as cigarettes, alcohol, coffee, chocolate, fizzy drinks non-herbal teas (Caffeine takes 8 hours to metabolize). Sleep is often disturbed in smokers and those who withdraw from heavy nicotine use. Although alcohol helps to fall asleep but the sleep will be very poor quality & fragmented. Regular exercise improves your sleep (although do not exercise close to bed time). Go to bed as early as possible and create a pattern of going to bed and waking up at the same time.

bookmark_borderFloaters In The Eye

The vitreous humor is the liquid or gel like substance in the eyeball. It is the medium between the lens and the back of the eye where the retina is located. The cause of floaters is when bits of tissue from the lining of the vitreous humor become loose. They are free to float around in the vitreous humor and will occasionally interfere with the line of sight causing the irregular shapes.

The bits of tissue that come loose is generally a consequence of aging or could be caused by wear and tear or accidents that have occurred. It might also be caused by posterior vitreous detachment. This is mainly a harmless event in the eye but will cause the increase in floaters. It generally only lasts a few days and then the floaters tend to disappear. However if the floaters continue after a few days it is a good idea to see your doctor. The same applies to flashes. Flashes are more disruptive than floaters because they flare up and can make it hard to concentrate on the image. If they continue for more than a few hours you should see your doctor.

In most cases floaters and flashes are not harmful to the eye and are more of an annoyance than anything else. When you first notice the floaters you may become a bit concerned but you will soon adapt to them and learn to ignore them. Of course, as already mentioned, if you notice that the number is increasing over a short space of time then you should consult your doctor as this may be an indication that something has changed in the interior of the eye.

bookmark_borderLasik Recovery Time

  • First Day After Surgery – Most people can return to their normal routines a day after the surgery. You will need to regularly use antibiotics, steroids, and other medications for your dry eye syndrome. Do not rub your eyes for the first 7 days and, while showering, do not let the water strike you on the face directly. Soap and shampoo in the eyes should be avoided strictly. Computer work, watching TV, and reading are acceptable, provided you lubricate your eyes regularly, and blink frequently. Light exercises are OK, but keep the sweat out of your eyes.
  • One Week After Surgery – Avoid touching your eyes, as well as keep sweat out of your eyes. Exercises are fine, but avoid swimming, whirlpools and hot tubs. Keep your eyes well lubricated, and use lotions, creams and eye makeup with care, unless advised to the contrary by your doctor.
  • Three Weeks After Surgery – Strenuous sports, including swimming, can be started, but with eye protection. You can start outdoor activities, but ensure that your eyes are well protected.
  • 3 to 6 Months After Surgery – It will take, at least this much time for your vision to stabilize. Fluctuating vision is part of the healing process and will take time to recover.

You may need re-surgery to correct certain anomalies. It is imperative that you follow your doctor’s instructions after the surgery. LASIK recovery time depends on the care you take with your eyes.

bookmark_borderWavefront Technology

Wavefront technology guides and optimizes LASIK procedures and offers a more sophisticated technique for calculating optical aberrations in your vision. Ophthalmologists now have tools for assessing and treating higher as well as lower order optical aberrations .

The lower order aberrations

Traditional LASIK has treated these three conditions for many years.

  • Myopia (nearsightedness)
  • Hyperopia (farsightedness)
  • Astigmatism (oval or irregularly shaped cornea which causes blurred or double vision)

The higher order aberrations

Wavefront-guided LASIK can do more: it diagnoses and treats these more elusive and puzzling eye conditions such as:

  • Halos – radiating circles around lights at night
  • Ghosting – faint duplicate images
  • Double vision – more definite duplicate images
  • Coma – points of light looking like little comets with blurry tails
  • Glare – over-bright appearance of lights at night

These subtle visual impairments are talked about in mathematical terms and require an understanding of optics. Your LASIK surgeon can diagnose them in your vision when he examines the way light rays are reflected back from your eyes to his Wavefront system. Every human eye is unique in its combination and severity of vision features. Wavefront technology allows your eye surgeon to map your two eyes exactly, and to use those two maps to guide the laser during your procedure. That’s why it’s called Custom LASIK.

Wavefront-Guided Diagnosis

One experienced Custom LASIK surgeon is Dr. Jonathan Davidorf in West Hills, California. His website. gives more information and offers you an online form for asking your questions about it. You could also schedule a consultation to see if you might be a candidate for Wavefront-guided LASIK.

After you’re comfortably seated at the Wavefront system, you gaze at a field and focus on an object. A light is shone into your eye. These straight light waves are reflected back from your eye to the machine that sent them, but only from a perfect eye would they reflect back as straight waves. They are distorted by your eye’s particular shape. The computer in the Wavefront system converts this information into a 3-Dn optical map, showing your eye’s unique flaws.

Wavefront sensing maps out where the exiting beams of light end up and records it. The wavefront map contains almost 2,000 data points, so your doctor has an extremely detailed map of your eye.

When ophthalmologists conduct an evaluation, wavefront technology gives them personalized diagnostic information about you. Because of this, LASIK surgeons have more information on which to base an informed decision and make recommendations about your best treatment option(s). They can devise a very subtle and detailed treatment plan for you.

Wavefront-Guided Treatment

The information gathered and recorded by the Wavefront technology is used like a road map, guiding the refractive surgeon as he applies the laser for your treatment. He can sculpt the cornea so that it treats the myopia, hyperopia, astigmatism, and higher order aberrations all at the same time. The doctor is able to tailor the LASIK procedure to each individual person, making the results more exact. Wavefront technology offers people the benefits of crisper, sharper, superior-quality vision correction while at the same time reducing higher order aberration side effects such as night vision problems of glare, ghosts, or halos.

Wavefront technology accesses formerly inaccessible information. This, in turn, allows doctors to apply more precise and customized treatments.

Since LASIK is the most common form of vision correction surgery, wavefront technology makes a good thing even better by improving the results and decreasing complications. Because wavefront-guided LASIK allows ophthalmologists to customize your treatment, you can expect the highest quality of vision correction to be achieved.

There are some factors that have been found to be linked to AMD, such as advancing age, genetic inheritance, smoking, nutrition, sun exposure and high blood pressure. The one factor that is the most under your control is nutrition. Eating the right foods may help decrease your risk of developing macular degeneration.

AMD is divided into two types, wet and dry. Wet (neovascular) AMD occurs when vessels keep forming to help the blood supply to the retinal tissue which is very oxygen deprived. The vessels that form are very fragile and easily break. This causes damage and bleeding to the tissue. Wet AMD is much more severe than dry AMD. The dry form (non-neovascular) is much more common and is characterized by loss of pigment within the retina.

Doctors have found that people who consumed the largest numbers of vegetables had a 43% lower risk of getting AMD than people who ate the least amount of vegetables. It can’t be just any vegetable though; it must be rich in carotenoids. Vegetables that contain the most carotenoids are spinach, collard greens and kale. Other vegetables also contain it though, just in fewer amounts. These vegetables, from the highest amount to the lowest amount, include parsley, mustard greens, dill, celery, scallions, leeks, broccoli, leaf lettuce, lettuce, green peas, pumpkin, brussel sprouts, summer squash, corn, green beans, green pepper, green olives and tomatoes. You should include an abundance of these vegetables in your diet.

There are many dietary supplements that you can take to slow the progression of AMD. Vitamins such as vitamin E, C, zinc and beta-carotene have been known to help. You can take a high dose of these supplements; however, this can be a risk for some people. Beta-carotene can increase the risk of lung cancer in smokers. Please talk to your doctor before beginning a high dose regimen. It is possible to lower your risk of developing advanced macular degeneration by 25% if you take this combination of vitamins.

There are still a few other things you can do to increase your risk. If you smoke, you should quit. Smoking hurts circulation in the body and causes the blood vessels in the retina not to work as efficiently. Wearing sunglasses regularly can also help protect your eyes. Even though you cannot see ultraviolet (UV) light, it is still absorbed by your eyes and eyelids. The sunglasses you get need to block all UV rays, which are UVA, UVB and UVC. Also, exercise regularly; this will increase your overall health and your circulatory system.

 

bookmark_borderTips for Dry Eyes

Smoking: Simple…Quit. Smoking has been shown to dry out your eyes. In addition, smoking increases the risk of cataracts, glaucoma, and macular degeneration.

Automobile Air vents: Vents pointed at your face and eyes can quickly drain the moisture in your eyes. Make sure to aim the vents away from your eyes or wear sunglasses for protection.

Omega-3: A recent study out of Japan has found that omega-3 supplementation could help prevent dry-eye syndrome.

Vitamin A: Taking a vitamin A supplement or eating vitamin A rich foods such as salmon or eggs can help keep your eyes moist.

Blink: In the electronic age, many of us spend a good deal of time staring at a computer screen. This can irritate even mild cases of dry eyes. When you are concentrating, you tend not to blink as much. Not blinking as frequently will make eye moisture evaporate rapidly. Ever so often, look away from your computer (or television) and take a blink break. Your eyes will thank you.

Humidify: Low moisture levels can dry your eyes fast. The winter can be especially drying during sleep. If possible, get a humidifier for the areas in which you spend a lot of time.
Your eyes are one of your most prized possessions. Think for a second what life would be like without them. It is important not to take them for granted. I hope the above remedies help, if not or if the problem persists, get to an eye doctor.
